German prosecutors have recorded calls between VW bigwigs talking dieselgate

It's barely possible to believe how poorly Volkswagen continues to handle dieselgate. Depending on which day you catch the news, the German carmaker embodies the corporate venality of "Michael Clayton," the comic blundering of the Coen Brothers' "Burn After Reading," and the every-man-for-himself vengeance of "Reservoir Dogs." Today is Tarantino day, with news that German prosecutors have recordings of phone calls between former Audi and Porsche development boss Wolfgang Hatz, ex-Volkswagen Group executive Matthias Muller, and current Porsche executives Oliver Blume and Michael Steiner. Hatz made the calls to the trio in November 2015, two months after Volkswagen admitted its diesel-particulate sins to the U.S. Environmental Protection Agency. Hatz was still employed at the time, and in his company car. Who recorded the calls? His wife. Hatz and his missus apparently saw the storm coming and started stacking defenses early. Hatz's wife, who can be heard encouraging Hatz during at least one call, sent the recordings to Hatz's attorney from her mobile phone. According to a Google translation of the German newspaper Handelsblatt's report, she included the note, "Here is a very long, but quite informative conversation on the current situation with useful formulations." The report in Handelsblatt said that in Germany it is generally "not allowed" to record a conversation and pass it on to a third party. We don't know how the authorities will handle this matter, since prosecutors found the recordings in e-mail attachments on Mrs. Hatz's mobile phone. Remember, when the diesel scandal broke, VW spent months saying that only a small number of low-level personnel were behind it, and all of the higher-ups had been blindsided. Ex-CEO Martin Winterkorn claimed to be "stunned that misconduct on such a scale was possible in the Volkswagen Group." Winterkorn successor Matthias Muller said, "according to current information, a few developers interfered in the engine management." Former VW USA honcho Michael Horn told a congressional committee that "a couple of software engineers" programmed the software for reasons no one could understand. In the recorded conversations, Hatz apparently called Muller to find out how VW planned to treat him.

Recharge Wrap-up: Tesla software suggestions, 'Audi at home' car sharing

Norwegian Tesla buff Bjorn Nyland wants the Tesla community to offer suggestions for the Firmware 7.1 over-the-air update. 7.0 includes a variety of small changes to the interface design, which Nyland discusses in depth in the video above. He offers constructive criticism, especially for things like the placement of certain data within the display. He calls upon other drivers to suggest their own changes and features they'd like to see in future updates. Nyland plans to tweet at Elon Musk once there are enough comments with hopes that Tesla will take the community's suggestions into consideration. See the video above, and read more at Teslarati. A survey of NRG eVgo stations found that drivers use DC fast charging over Level 2 charging by a ratio of 12 to 1. While businesses might prefer to install a Level 2 charger because it is cheaper and could help convince the customer to linger longer while they wait for a charge, this study suggests that DC charging could actually be a better way to attract customers. But the question is how to make DC charging sustainable for businesses with regard to the costs. Read more at Green Car Reports. Audi is launching its vehicle sharing program at luxury residences in San Francisco and Miami this week. Called "Audi at home," the program provides residents with a fleet of Audi vehicles at their disposal at either hourly or daily rates. The cars – the S7, S5 Cabriolet, SQ5, TT Roadster, Q7, and RS5 Cabriolet – are all of the Prestige trim level. Drivers needn't worry about mileage charges, tolls, fuel costs, insurance, or cleaning. Just reserve the car online, and drop it off at the property's valet when finished. Audi at home is launching at the Lumina luxury condos in San Francisco and at the Four Seasons Residences in Miami, with expansion to more cities planned for the future. Read more from Audi. Ballard is partnering with bus manufacturer King Long to build fuel cell buses in China. The two companies will work together to design and deploy the hydrogen-powered buses first in China, then in King Long's global network. "We are delighted to be working with the second largest bus OEM in the world on this important fuel cell bus design and market opportunity," says Ballard President and CEO Randy MacEwen. "Together, we are looking to optimize the design in order to improve performance, while lowering cost.

Porsche offering 250-hp 718 Cayman, Boxster in China

Porsche is studying a new approach in the lucrative Chinese market – less power. Automotive News Europe reports that the famed German manufacturer will sell less powerful versions of the 718 Cayman and Boxster in the People's Republic. In fact, the new cars are already on Porsche's Chinese consumer page. The hope, 718 chief Jan Roth told Automotive News Europe, is to replicate the success Porsche's sister company Audi has had with the TT. "A lot of the TTs that Audi sells in China, the smaller displacement 1.8-liter versions with rear-wheel instead of all-wheel-drive, are priced below that, Mercedes too," Roth said. We're guessing the comments about rear-wheel drive and a 1.8-liter engine are either typos or something was lost in translation, because Audi's Chinese website only lists a 2.0-liter engine, and most gearheads know the TT rides on a front-drive platform. Audi's success is largely down to price – 542,800 yuan ($81,549, at today's rates) for a base TT. Roth called 600,000 yuan "a magical threshold for customers in China." To hit that price point, Porsche is dropping the 718's 2.0-liter, turbocharged four-cylinder – offered North America and Europe with 300 horsepower in base form – to 250 ponies. The Cayman starts at 588,000 yuan ($88,340) while the Boxster is 598,000 yuan ($89,842). The 350-hp Cayman S will carry on unchanged. According to ANE, Roth said Porsche's Chinese strategy could drive 718 sales up to 4,500 units a year by 2017, nearly double the 2,500 Boxsters and Caymans sold in 2015. Could a similar lower-tiered strategy work in the US? We'll need to put on our speculation hats. In the US, the base car is about 81 percent of the price of the 350-horsepower S model. If Porsche were to offer the same discount for the hypothetical, 250-hp 718s, it could set the starting prices at $43,659 for the Cayman and $45,360 for the Boxster. That lines up neatly with the $43,500 TT Coupe, but this theoretical 250-hp Boxster would fall about $1,640 less than Audi's soft top. We shouldn't forget Porsche's expansive options catalog – we doubt there'd be a lot of sub-$50,000 718s on dealer lots. But still, slashing over $10,000 off the price of a $54,000 car is a big ask – Porsche would almost have to de-content such a lower-tier model. But – and this is a Kim K-sized but – moving the 718 downmarket would open the brand to a new range of consumers. Not only would these new cars be the cheapest sportscars from Porsche money could buy.
